본 발명은 헤드램프와 야간시계 확보용 시스템의 적외선램프를 일체로 하여 사용함으로써, 자동차의 램프가 차지하는 자동차의 전면부 외관을 깔끔하게 처리할 수 있으며, 상기 적외선램프를 별도로 적용하지 않게 되어 부품 및 중량이 감소됨에 따라 비용을 절감시킬 수 있는 발명이다. According to the present invention, by using the head lamp and the infrared lamp of the night vision securing system integrally, the front part of the front of the vehicle occupied by the lamp of the vehicle can be neatly processed, and the infrared lamp is not applied separately. As this is reduced, the invention can reduce the cost.

도 1a와 도 1b에 도시된 바와 같이, 헤드램프(10)는 여러가지 구성부품으로 이루어져 있는 바, 렌즈(11)와 용기형상의 헤드램프 하우징(12)으로 외형이 구성되어 있으며, 상기 헤드램프 하우징(12) 내에는 그 램프 하우징의 후방에 형성된 소켓(18)에 끼워진 광원인 벌브(13)와, 상기 헤드램프 하우징(12)의 내벽에 일체로 구성되어 벌브의 광을 전방으로 반사하는 반사경인 리플렉터(14) 등으로 이루어져 있다. As shown in Figure 1a and 1b, the headlamp 10 is composed of various components, the outer shape is composed of a lens 11 and the container headlamp housing 12, the headlamp housing Inside the 12 is a bulb 13, which is a light source fitted to a socket 18 formed at the rear of the lamp housing, and a reflecting mirror which is integrally formed on the inner wall of the headlamp housing 12 and reflects the light of the bulb to the front. The reflector 14 etc. are comprised.

한편, 상기 벌브(13)에서 산란되는 광을 모아 리플렉터(14)로 다시 반사시키는 기능을 하는 실드(shield)(15)가 상기 벌브(13)와 일정한 간격을 두고 연장되어 있는 원형구조로 배치되어 있다.On the other hand, a shield (15) having a function of collecting light scattered from the bulb 13 and reflecting back to the reflector 14 is arranged in a circular structure extending at regular intervals from the bulb (13) have.

이때, 상기 실드(15)와 리플렉터(14) 사이에는 실드(15)가 일정한 간격을 두고 이격되어 고정될 수 있도록 하는 이음부(16)가 일체로 형성되어 있다.In this case, a joint 16 is integrally formed between the shield 15 and the reflector 14 so that the shield 15 may be spaced apart and fixed at regular intervals.

본 발명의 바람직한 구현예에서, 상기 이음부(16)에는 적외선필터(17)가 설치되어 있는 바, 이는 상기 벌브(13)에서 조사된 광이 적외선필터(17)를 통해 투과되어 적외광을 조사할 수 있도록 하기 위함이다. In a preferred embodiment of the present invention, the joint portion 16 is provided with an infrared filter 17, which is irradiated with infrared light by the light irradiated from the bulb 13 through the infrared filter 17 To do that.

상기 적외선필터(17)는 도 1a에 도시된 바와 같이, 투명재질로 이루어진 이음부(16)의 표면에 부착된 구조이거나, 도 1b에 도시된 바와 같이, 그 자체를 이음부(16)로 하여 장착한 것이 바람직하다.As shown in FIG. 1A, the infrared filter 17 is attached to the surface of the joint 16 made of a transparent material, or as shown in FIG. 1B, as the joint 16. It is preferable to attach.

이때, 상기 적외선필터(17)는 본 발명의 바람직한 구현예에서 원형으로 이루어진 리플렉터(14)의 적어도 1/3 구간에 걸쳐 적외선 투과 영역이 분포되도록 되어 있는 바, 원형의 실드(15)에 일체로 연장되어 있는 동시에, 그 실드(15)의 하단 외주면에 상기와 같은 투과 영역이 분포될 수 있도록 적어도 1/3 구간에 형성된 원호구조로 되어 있다. At this time, the infrared filter 17 is an infrared transmission region is distributed over at least one third of the circular reflector 14 in a preferred embodiment of the present invention, integrally with the circular shield 15 At the same time, it has an arc structure formed in at least one third section so as to distribute the above-mentioned transmission region on the outer peripheral surface of the lower end of the shield 15.

따라서, 상기 적외선필터(17)가 적용되어 있지 않은 벌브(13)의 상부로는 일반적인 가시광선이 리플렉터(14)에 반사되어 전방으로 조사되며, 적외선필터(17)가 적용된 벌브(13)의 하부로는 상기 적외선필터(17)를 투과한 적외광이 리플렉터(14)에 반사되어 전방으로 조사된다. Therefore, the upper part of the bulb 13 to which the infrared filter 17 is not applied is irradiated forward by the general visible light reflected by the reflector 14, and the lower part of the bulb 13 to which the infrared filter 17 is applied. In the furnace, infrared light transmitted through the infrared filter 17 is reflected by the reflector 14 and irradiated forward.

이와 같이 본 발명에 따른 자동차의 헤드램프 및 적외선램프 일체형 구조는 헤드램프 및 적외선램프를 별도로 분리하여 장착하지 않고, 기존의 헤드램프에 적외선필터만을 적용한 간단한 램프구조로서, 자동차 전방을 조사하는 기능뿐만 아니라, 야간시계 확보용 시스템(NIGHT VISION SYSTEM) 기능을 하나의 램프에서 복합적으로 수행할 수 있는 신개념의 램프인 것이다. As described above, the integrated structure of the head lamp and the infrared lamp of the vehicle according to the present invention is a simple lamp structure in which only the infrared filter is applied to the existing head lamp, without separately mounting the head lamp and the infrared lamp. Rather, it is a new concept lamp that can perform the night vision security system function in one lamp.

상술한 바와 같이, 본 발명에 따른 자동차의 헤드램프 및 적외선램프 일체형 구조는 야간시계 확보용 시스템의 적외선램프를 별도로 차체 전면부에 적용하지 않고, 그 기능을 단일개의 헤드램프에서 구현할 수 있도록 벌브의 하단부에 적외선필터를 설치함으로써, 차체에서 램프가 차지하는 면적을 줄여 미려한 외관을 도모할 수 있고, 그로인한 부품 및 중량의 감소를 도모하여 장착공정 또한 축소할 수 있으며, 결국에는 자동차의 원가를 절감할 수 있는 효과가 있다. As described above, the head lamp and infrared lamp integrated structure of the vehicle according to the present invention does not apply the infrared lamp of the night vision securing system to the front of the vehicle body separately, so that the function of the bulb can be implemented in a single head lamp By installing an infrared filter on the lower part, it can reduce the area occupied by the lamp in the car body and achieve a beautiful appearance. Therefore, the mounting process can be reduced by reducing the parts and weight, thereby reducing the cost of the car. It can be effective.

또한, 헤드램프와 적외선램프 기능을 하나의 벌브를 이용하여 복합적으로 사용하므로 기존의 헤드램프 미작동 상태에서 적외선램프를 작동시켰을 경우에 발생할 수 있었던 미등이나 브레이크등의 점등으로 오인할 오해의 소지에서 벗어날 수 있는 효과가 있다. In addition, since the head lamp and the infrared lamp function are used in combination with a single bulb, it may be misunderstood as lighting of tail lights or brake lights that may have occurred when the infrared lamp is operated while the existing head lamp is not in operation. There is an effect to escape.
